I've been flying my Hoverthings HT-FPV successfully for the last 6 months and having a ball.
I've however been saving up my pennies and purchased a 3D printer, and a CNC router unit to join my trusty old Laser engraver. I've bought these with making MR frames in and accessories in mind.
I love throwing my TX, batteries etc in my back pack, and strapping the HT-FPV on the back, but have found more often than not I'm getting loads of undue attention from rubber-necking passers-by, and also catching the widespread props/arms on tress, bushes, doorways etc.
Taking some ideas of the Hoverthings range (6mm G10 for arms, as used in Tom's Flip), some of the FPVManuals (QAV layout, with clean plate), even some parts from jDrones (Vibe dampeners) and Droidworx, I'm slowly getting my own flying wet dream into shape!
Currently working on it to use either Coptercontrol CC3D/Revo, or the APM range, I can't wait to get it airborne. It's a square motor layout, 350mm size.
I'm also working on the add-on module for the front, to either mount a fixed GoPro1 or 2, another for the GoPro3. These will mount on the clean plate and extend out front to clear 8" props, with provision for shifting if 10" props are in use. Standard FPV camera fits snugly underneath.
This add-on approach means the configuration can be cheaply, quickly changed out, and most of all, leaves room for the range of Brushless Gimbals about the flood the market, which I'm very excited about!
Entire profile should not exceed the height of the motors, as I've found with Tom's excellent HT-FPV, it has very little issue penetrating into strong winds.
Non-flying, mock up/Prototype is 2mm laser-cut acrylic, with cnc-routed 6mm Signex arms/pockets. Gear onboard is mostly based on Juz's ht-fpv rig, see www.juzfpv.com
Very nice - my similar idea, different implementation: http://www.diydrones.com/profiles/blogs/epp-foam-folding-h-frame-quad
These folding H's are the way to go!
Thanks Graham, I just stumbled upon that this morning, very similar indeed. We're all wanting the same thing, gotta love the open community, some great ideas floating around. I'm interested in the EPP foam, as I used expanded PVC "signex" "Foamcore" for this mock up. Too flexible for arms, but really light, cheap, easy to mill and smells like coconuts, yum! I'll hunt down some locally, see how it mills. Cheers for your comments.
Hey guys, I'm new to quad and am about to put together my first one!
I want something foldable and compact enough to bring on a hike and film some stable shots. This looks perfect.
Would a quad this size be able to lift a gopro and a gimbal system?
Also, what's the relation between weight, size and stability when it comes to filming from a flying platform?
Any tips ? :)
Hi Thierry, I've designed this first and foremost around the GoPro Hero3, and a brushless gimbal system, which is yet to release to the market. I'll be buying the controller, and motors, then making up the gimbal frame myself, and hope that the community will develop some solid Alexmos code into the APM so it can piggy back on its IMU.( I don't understand the thought a separate IMU needs to be on the camera itself). As Graham puts it, above, "folding H's are the way to go!"
Maybe see what the QAV pilots have say, as their monolithic arms might be very easily removed to make a quickly assembled aircraft. For now, it's a race to get an affordable, foldable H frame to the market!
I'm about to do a very similar design, and that new picture you just posted makes it look really slick.
I think the QAV frames aren't that quick to take apart and rebuild, at least no on the go. Perhaps you should sell your frame as a kit online :) Especially now that you have a CNC machine, you can replicate them easily!
Do you have any flight videos of your foldable rig?
I'm currently shopping for parts and have a hard time figuring out what prop size and motor power are good to achieve a stable flight with the gopro.
What's the motor/prop combo you have on yours?
Hi Thierry, thanks for your kind words. I only just a test flight in last night. It wobbles a little, which I'll tune out, and there's a little flex in the main "dirty" section, which I'll brace with something, but overall I'm really happy.
Check out my other post at Openpilot for my specs:
It should carry another 300-350g perfectly as I've used this combo before. Once I've got this puppy tuned in, I'll start working on the payload module for mounting on the front.
Hey, This is really cool, I'm interested in making something like this. Can we please discuss over PM ?
Sure Kabir, This, version 4 craft is already sold to a customer, RTF. I'm halfway through a version 6 now.
It's 440 size, but has several improvements, namely less downdraft drag from the props as the arms are longer, but it also folds neatly now WITH PROPS ATTACHED.
Wizeartz is now up and running, and work on Version 6 is stalled whilst I try to tune in Alt Hold on the Version 4 I sold to a customer. Bloody things oscillates, losing alt, and eventually lands. Any hints folks?
I sent you a PM :)
